Changes could be on the way into America's Hometown.
The Hannibal City Council voted to allow MoDOT to examine costs associated with improving Mark Twain Avenue.
City Manager Jeff LaGarce said the department is scheduled to repave that road in 2015 and rebuild the sidewalks to make them more accessible.
In the process, MoDOT came up with some possible improvements for Mark Twain Avenue, which include bike paths on both sides of the road, ornamental lighting, green space and trees.
A department representative told the council five lanes are not needed based on current traffic patterns.
Mark Twain Avenue would become three lanes, rather than five under the proposal.
MoDOT would pay for the base cost, and the city would pay anything beyond that.
"This might be something we can fund without any out-of-pocket expense and make Mark Twain Avenue, which is a key corridor link from Highway 36 to our downtown historic district, make it a nice, attractive corridor for Hannibal residents and tourists," LaGarce said.
MoDOT now will put together an engineer's estimate to let the city know how much the improvements would cost and whether there's enough funding available.
